Abstract

In this study, prepared synthesis waterborne acrylic resin and water soluble milk casein resin. And than extent of casein contents in acrylic resin. We measured property of these samples by Lamb leather which is coated by acrylic-casein resins. According to measure data for solvent resistance, WAR resin and Hybrid resins had good property. Among this result knew that increase of casein constant did not influence to big change of hybrid resin property. As test of tensile strength, WAR had lowest strength($1.399kg_f/mm^2$) and WAC-3 had highest strength($1.426kg_f/mm^2$). Also we knew that best property of abrasion was WAC-3(69.774 mg.loss). In elongation case, WAR had best property(820%) in this experiment.

본 연구에서는 수용성 아크릴을 합성한 다음 수성 카제인 수지를 합성하여 기합성 완성된 아크릴 수지에 카제인 수지의 적하량을 점차 증가시켜 변화하는 물성을 피혁(Lamb leather)에 표면 코팅하여 물성을 측정 분석하였다. 내용제성 측정 결과 높은 내용제성 물성을 지닌 아크릴 수지와 카제인 수지의 함량이 물성 변화에 끼치지 않았으며 모두 높은 물성치를 나타내었다. 인장 강도 측정치에서는 아크릴 단독 코팅의 측정치가 $1.399kg_f/mm^2$로 가장 낮은 수치를 나타내었으며, 카제인 수지의 합량이 제일 높은 WAC-3가 가장 높은 인장력 $1.426kg_f/mm^2$을 나타내었다. 또한 내마모도 측정에서는 WAC-3가 제일 높은 69.774 mg.loss로 우수한 물성변화를 나타내었고, 연실률의 경우 아크릴 단독 코팅인 WAR이 820 %로 가장 높은 수치를 나타내었다.
